SUMMARY
The horizontal component of a volleyball's velocity when spiked at an initial velocity of 15 m/s and an angle of 55 degrees below the horizontal is calculated using the formula for horizontal velocity. The calculation yields a horizontal velocity of 8.6 m/s, derived from the equation: horizontal velocity = velocity * cos(angle). This confirms that the approach and calculation are correct, providing a definitive answer to the problem presented.
